Improve styling

[VatsKan]

• styling: log out and create new post underlines or overlines on hover (not sure if this is intentional).
• would be cool to see styling on edit and delete buttons also.
• Also delete and edit buttons float to the right on short snippets.

(NB styling is incredible otherwise! <3)

Agreed on those three points above. There was a lot to get in this week and you've done an impressive job on styling considering. Certainly worth bringing those buttons up to the standard of everything else!
